SROM Mini-Debugger Command Set 3–41
User Commands
sb
The set base (sb) command defines the base address to be added to user-specified
addresses when the base flag is enabled.
Control Flags
Not applicable.
Description
Using a base address is convenient when examining or depositing of the same
address frame is needed (particularly when the high-order bits of the address must be
set). The base address entered with the set base command is added to the addresses
entered in any subsequent examine or deposit commands, saving the user some
typing. This command always enables the base flag.
Example
To access a flash ROM part that responds to addresses 3.FFF80000 through
3.FFFFFFFF, it may be more convenient to enter its base address and work with
offsets, rather than typing the absolute address every time.
